Hi, when you have a little play from side to side just shows very little bearing wear on the blower motor. In and Out play is normal. Spin the wheel to see if it is true. If the blower wheel has a lot of dirt build up on the blades it will cause it to be out of balance.If it is clean, but warped, take it to a motor repair shop along with the model and serial numbers. Call you're local wholesale a/c parts house with all of your info and they will look this up for you.The numbers that you have listed shows you have a 042 which is a 31/2 ton and 048 which is a 4 ton unit. More then likely, the wheel is out of balance and should be replaced, and they can look up the info you are requesting. Good Luck,

2013 Edge. Blower motor is fine,BUT NO heat...????


Hello, Sounds like the flap that controls the cold air and hot air duct is not working. One duct pulls air through the heater core where the other duct draw air from the outer vent. If that flap is not working, allowing you to pull from the heater core duct, then either the switch/lever that controls the flap is faulty (more likely) or the flap is stuck (less likely). Hope this helps.

No AC


Turn off power, if this is a complete outdoor unit, remove the blower door Turn Unit back on see if the blower motor is working. If belt driven belt is loose or off, if direct drive and the fan is not working, its possible the capacitor is bad or fan is bad.

If fan is operating, then either a damper is closed, something is obstructing the duct or it is at to low
of speed.

Rheem A/C unit makes a clicking sound when


Shut down the unit and turn the power off. Take the cover off of the blower housing and feel around within the squirrel cage. It sounds like something may have been drawn up into the blower. Also it is possible that the blower wheel might have thrown a balance weight and caused the wheel to become unbalanced. It could also be the motor about to go out but since I can't hear it myself, I'm trying to cover all the bases.

Carrier A/C Intermittent Shut-down Problem


It sounds like there is something in the system that is over heating. A t-stat will either work or it won't there are relays that have 24v coils and can become weak. If your air handler is shutting down it shut down the condenser, if the air handler is staying on but condenser is shuting down check the outside contactor. I am an a/c contractor and can be contacted at 504-722-3946 Eddie.
